Well, I still have an electric carving knife, and if I hadnt had one for the last ten years, I would not have ever cooked a roast dinner, because I hated carving meat with just an ordinary knife.
I recently bought one for my mum, because we go over there for a roast dinner nearly every Sunday, but I must admit, I wont let her use it, as she is 80, and I worry that she wont be able to manouvre it without cutting off a finger or something......so when we go over for dinner, I take on the job of cutting the roast.....with the electric knife.......it is so quick eand easy......
.......I thought EVERYONE owned and used one.....and when I saw it in the movie, I thought that was a pretty common occurence....
